Fatal error while initializing | Forum

Fatal error while initializing Unreal project.

Hello - I've been stuck on a issue. I'm running Studio 2025.1.0. I can cook a scene using Unreal Editor for Aximmetry, however when I try to bring this project into the Composer, I get the following errors on the screen (please see snapshots below).

I have no errors when cooking. In Unreal Editor for Aximmetry I've tried both the "Tracked_cam_1-3_Billboards" and the "Virtual_cam_1-3_Billboards". Both have cooked successfully. I do have Visual Studio 2022 installed and configured per documentation..

This unreal project is the CitySample (Small level). I did see another thread on the forum that some folks were successful and I've followed the same steps that I can determine. Only difference I can see is the thread referenced 2024.x.x and I'm using 2025.1.0.

Any thoughts how I can get past this?

thanks!

Hi,

Did you rename your Unreal project file at any point? Renaming can disrupt the cooking process.

Additionally, Unreal Engine projects are sensitive to their file system locations.
Avoid spaces and non-ASCII characters: Stick to standard ASCII letters, numbers, hyphens, and underscores in folder and file names. For example, MyGame_Project-01 is a safe option.
Keep the total path length under 200 characters: This gives you a safety margin below Windows' 260-character maximum path length. So, place your projects in a shallow directory, such as C:\UnrealProjects\MyUnrealProject, instead of deeply nested folders like C:\Users\YourName\Documents\Projects\MyCompany\MyUnrealProject.

Additionally, try using the "Cook Content for Aximmetry DE (Debug)" option. This can produce more detailed error messages before a fatal error occurs, making it easier to identify and resolve the issue. You can find more information about debug cooking here: https://aximmetry.com/learn/virtual-production-workflow/obtaining-graphics-and-virtual-assets/creating-content-for-aximmetry-de/preparing-the-unreal-project/#cooking-the-project-for-aximmetry

thank you Eifert for the response. I will look at the directory naming structure, however, note that I don't have problem cooking. The issue/errors happens when I try to bring in the Unreal project into Aximmetry composer.

Does Aximmetry Composer have directory/file name restrictions too?

thanks

Hi,

Well, the 260-character maximum path length also applies to Aximmetry and Windows in general. People are just more likely to run into that with Unreal, because Unreal has very long internal folder structures.
Also, Aximmetry can handle non-ASCII characters and space characters.

Warmest regards,
